When calculating frequency, what would happen if the RPM is set to zero?

When the RPM (revolutions per minute) is set to zero, it indicates that there is no rotational motion occurring in the system. Frequency, measured in Hertz (Hz), reflects how many cycles per second occur in a periodic signal or wave. In the case of an electrical generator or motor, the frequency is directly related to the RPM.

To find the frequency in an electrical context, you typically use the formula:

[ \text{Frequency (Hz)} = \frac{\text{RPM}}{60} ]

If RPM equals zero, substituting this value into the formula yields:

[ \text{Frequency (Hz)} = \frac{0}{60} = 0 , \text{Hz} ]

This indicates that the frequency is 0 Hz, meaning there is no output of alternating current (AC) because there is no mechanical motion to generate electrical cycles. Thus, a setting of zero RPM leads directly to a frequency output of 0 Hz, as there are no events or cycles occurring.
